The invention relates to the seeds of garden bean cultivar H24953, to the plants of garden bean line H24953 and to methods for producing a bean plant by crossing the cultivar H24953 with itself or another bean line. The invention further relates to methods for producing a bean plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other garden bean lines derived from the cultivar H24953.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinctive garden beancultivar (Phaseolus vulgaris), designated H24953. All publications citedin this application are herein incorporated by reference.

There are numerous steps in the development of any novel, desirableplant germplasm. Plant breeding begins with the analysis and definitionof problems and weaknesses of the current germplasm, the establishmentof program goals, and the definition of specific breeding objectives.The next step is selection of germplasm that possesses the traits tomeet the program goals. The goal is to combine in a single variety animproved combination of desirable traits from the parental germplasm.

In beans, these important traits may include fresh pod yield, higherseed yield, resistance to diseases and insects, better stems and roots,tolerance to drought and heat, and better agronomic quality. Withmechanical harvesting of many crops, uniformity of plantscharacteristics such as germination and stand establishment, growthrate, maturity and plant height is important.

Choice of breeding or selection methods depends on the mode of plantreproduction, the heritability of the trait(s) being improved, and thetype of cultivar used commercially (e.g., F₁ hybrid cultivar, purelinecultivar, etc.). For highly heritable traits, a choice of superiorindividual plants evaluated at a single location will be effective,whereas for traits with low heritability, selection should be based onmean values obtained from replicated evaluations of families of relatedplants. Popular selection methods commonly include pedigree selection,modified pedigree selection, mass selection, recurrent selection andbackcross breeding.

The complexity of inheritance influences choice of the breeding method.Backcross breeding is used to transfer one or a few favorable genes fora highly heritable trait into a desirable cultivar. This approach hasbeen used extensively for breeding disease-resistant cultivars.Nevertheless, it is also suitable for the adjustment and selection ofmorphological character, color characteristics and simply inheritedquantitative characters. Various recurrent selection techniques are usedto improve quantitatively inherited traits controlled by numerous genes.The use of recurrent selection in self-pollinating crops depends on theease of pollination, the frequency of successful hybrids from eachpollination and the number of hybrid offspring from each successfulcross.

Each breeding program should include a periodic, objective evaluation ofthe efficiency of the breeding procedure. Evaluation criteria varydepending on the goal and objectives, but should include gain fromselection per year based on comparisons to an appropriate standard,overall value of the advanced breeding lines, and number of successfulcultivars produced per unit of input (e.g., per year, per dollarexpended, etc.).

Promising advanced breeding lines are thoroughly tested and compared toappropriate standards in environments representative of the commercialtarget area(s) for three or more years. The best lines are candidatesfor new commercial cultivars; those still deficient in a few traits maybe used as parents to produce new populations for further selection.

These processes, which lead to the final step of marketing anddistribution, usually take from eight to twelve years from the time thefirst cross is made. Therefore, development of new cultivars is atime-consuming process that requires precise forward planning, efficientuse of resources, and a minimum of changes in direction.

A most difficult task is the identification of individuals that aregenetically superior, because for most traits the true genotypic valueis masked by other confounding plant traits or environmental factors.One method of identifying a superior plant is to observe its performancerelative to other experimental plants and to a widely grown standardcultivar. If a single observation is inconclusive, replicatedobservations provide a better estimate of its genetic worth.

The goal of garden bean plant breeding is to develop new, unique andsuperior garden bean cultivars. The breeder initially selects andcrosses two or more parental lines, followed by repeated selfing andselection, producing many new genetic combinations. The breeder cantheoretically generate billions of different genetic combinations viacrossing, selfing and mutations.

Each year, the plant breeder selects the germplasm to advance to thenext generation. This germplasm is grown under unique and differentgeographical, climatic and soil conditions and further selections arethen made during and at the end of the growing season. The cultivarsthat are developed are unpredictable. This unpredictability is becausethe breeder's selection occurs in unique environments with no control atthe DNA level (using conventional breeding procedures), and withmillions of different possible genetic combinations being generated. Abreeder of ordinary skill in the art cannot predict the final resultinglines he develops, except possibly in a very gross and general fashion.This unpredictability results in the expenditure of large amounts ofresearch monies to develop superior new garden bean cultivars.

The development of new garden bean cultivars requires the developmentand selection of garden bean varieties, the crossing of these varietiesand the evaluation of the crosses.

Pedigree breeding and recurrent selection breeding methods are used todevelop cultivars from breeding populations. Breeding programs combinedesirable traits from two or more cultivars or various broad-basedsources into breeding pools from which cultivars are developed byselfing and selection of desired phenotypes.

Pedigree breeding is used commonly for the improvement ofself-pollinating crops or inbred lines of cross-pollinating crops. Twoparents that possess favorable, complementary traits are crossed toproduce an F₁. An F₂ population is produced by selfing one or severalF₁s or by intercrossing two F₁s (sib mating). Selection of the bestindividuals may begin in the F₂ population; then, beginning in the F₃,the best individuals in the best families are selected. Replicatedtesting of families, or hybrid combinations involving individuals ofthese families, often follows in the F₄ generation to improve theeffectiveness of selection for traits with low heritability. At anadvanced stage of inbreeding (i.e., F₆ and F₇), the best lines ormixtures of phenotypically similar lines are tested for potentialrelease as new cultivars.

Mass and recurrent selections can be used to improve populations ofeither self- or cross-pollinating crops. A genetically variablepopulation of heterozygous individuals is either identified, or created,by intercrossing several different parents. The best plants are selectedbased on individual superiority, outstanding progeny, or excellentcombining ability. The selected plants are intercrossed to produce a newpopulation in which further cycles of selection are continued.

Backcross breeding has been used to transfer genes for a simplyinherited, highly heritable trait into a desirable homozygous cultivaror inbred line which is the recurrent parent. The source of the trait tobe transferred is called the donor parent. The resulting plant isexpected to have the attributes of the recurrent parent (e.g., cultivar)and the desirable trait transferred from the donor parent. After theinitial cross, individuals possessing the phenotype of the donor parentare selected and repeatedly crossed (backcrossed) to the recurrentparent

The single-seed descent procedure in the strict sense refers to plantinga segregating population, harvesting a sample of one seed per plant, andusing the one-seed sample to plant the next generation. When thepopulation has been advanced from the F₂ to the desired level ofinbreeding, the plants from which lines are derived will each trace todifferent F₂ individuals. The number of plants in a population declineseach generation due to failure of some seeds to germinate or some plantsto produce at least one seed. As a result, not all of the F₂ plantsoriginally sampled in the population will be represented by a progenywhen generation advance is completed.

In a multiple-seed procedure, garden bean breeders commonly harvest oneor more pods from each plant in a population and thresh them together toform a bulk. Part of the bulk is used to plant the next generation andpart is put in reserve. The procedure has been referred to as modifiedsingle-seed descent or the pod-bulk technique.

The multiple-seed procedure has been used to save labor at harvest. Itis considerably faster to thresh pods with a machine than to remove oneseed from each by hand for the single-seed procedure. The multiple-seedprocedure also makes it possible to plant the same number of seeds of apopulation each generation of inbreeding. Enough seeds are harvested tomake up for those plants that did not germinate or produce seed.

Descriptions of other breeding methods that are commonly used fordifferent traits and crops can be found in one of several referencebooks (e.g., Principles of Plant Breeding, John Wiley and Son, pp.115-161, 1960; Allard, 1960; Fehr, 1987).

Proper testing should detect any major faults and establish the level ofsuperiority or improvement over current cultivars. In addition toshowing superior performance, there must be a demand for a new cultivarthat is compatible with industry standards or which creates a newmarket. The introduction of a new cultivar will incur additional coststo the seed producer, the grower, processor and consumer for specialadvertising and marketing, altered seed and commercial productionpractices, and new product utilization. The testing preceding release ofa new cultivar should take into consideration research and developmentcosts as well as technical superiority of the final cultivar. Forseed-propagated cultivars, it must be feasible to produce seed easilyand economically.

Garden bean, Phaseolus vulgaris L., is an important and valuablevegetable crop. Thus, a continuing goal of garden bean plant breeders isto develop stable, high yielding garden bean cultivars that areagronomically sound. The reasons for this goal are obviously to maximizethe amount of yield produced on the land. To accomplish this goal, thegarden bean breeder must select and develop garden bean plants that havetraits that result in superior cultivars.

The foregoing examples of the related art and limitations relatedtherewith are intended to be illustrative and not exclusive. Otherlimitations of the related art will become apparent to those of skill inthe art upon a reading of the specification.

When crossed with itself, i.e. when crossed with another beancultivar H24953 plant or self-pollinated, bean cultivar H24953 will beconserved. When crossed with another, different bean plant, an F₁ hybridseed is produced. F₁ hybrid seeds and plants produced by growing saidhybrid seeds are included in the present invention. A method forproducing an F₁ hybrid bean seed comprising crossing a bean cultivarH24953 plant with a different bean plant and harvesting the resultanthybrid bean seed are also part of the invention. The hybrid bean seedproduced by the method comprising crossing a bean cultivar H24953 plantwith a different bean plant and harvesting the resultant hybrid beanseed, are included in the invention, as are the hybrid bean plant orpart(s) thereof, and seeds produced by growing said hybrid bean seed.

In another aspect, the present invention provides transformed H24953bean cultivar plants or part(s) thereof that have been transformed sothat its genetic material contains one or more transgenes, preferablyoperably linked to one or more regulatory elements. Also, the inventionprovides methods for producing a bean plant containing in its geneticmaterial one or more transgenes, preferably operably linked to one ormore regulatory elements, by crossing transformed H24953 bean cultivarplants with either a second plant of another bean cultivar, or a nontransformed H24953 bean cultivar, so that the genetic material of theprogeny that results from the cross contains the transgene(s),preferably operably linked to one or more regulatory elements. Theinvention also provides methods for producing a bean plant that containsin its genetic material one or more transgene(s), wherein the methodcomprises crossing the cultivar H24953 with a second bean cultivar ofanother bean cultivar which contains one or more transgene(s) operablylinked to one or more regulatory element(s) so that the genetic materialof the progeny that results from the cross contains the transgene(s)operably linked to one or more regulatory element(s).

The transformed bean plants, or part(s) thereof, obtainedfrom the provided methods, including a male sterile bean plant, anherbicide resistant bean plant, an insect resistant bean plant, adisease resistant bean plant, a bean plant tolerant to water stress, abean plant tolerant to heat stress or a bean plant with improvedshelf-life are included in the present invention. For the presentinvention and the skilled artisan, disease is understood to be fungaldiseases, viral diseases, bacterial diseases or other plant pathogenicdiseases and a disease resistant plant will encompass a plant resistantto fungal, viral, bacterial and other plant pathogens.

In another aspect, the present invention provides for methods ofintroducing one or more desired trait(s) into bean cultivar H24953 andplants obtained from such methods. The desired trait(s) may be, but notexclusively, a single gene, preferably a dominant but also a recessiveallele. Preferably, the transferred gene or genes will confer suchtraits as male sterility, herbicide resistance, insect resistance,resistance to bacterial, fungal, or viral disease, increased leafnumber, improved shelf-life, and tolerance to water stress or heatstress. The gene or genes may be naturally occurring gene(s) ortransgene(s) introduced through genetic engineering techniques. Themethod for introducing the desired trait(s) is preferably a backcrossingprocess making use of a series of backcrosses to bean cultivar H24953during which the desired trait(s) is maintained by selection.

When using a transgene, the trait is generally not incorporated intoeach newly developed line/cultivar such as bean cultivar H24953 bydirect transformation. Rather, the more typical method used by breedersof ordinary skill in the art to incorporate the transgene is to take aline already carrying the transgene and to use such line as a donor lineto transfer the transgene into the newly developed line. The same wouldapply for a naturally occurring trait. The backcross breeding processcomprises the following steps: (a) crossing bean cultivar H24953 plantswith plants of another cultivar that comprise the desired trait(s); (b)selecting the F₁ progeny plants that have the desired trait(s); (c)crossing the selected F₁ progeny plants with bean cultivar H24953 plantsto produce backcross progeny plants; (d) selecting for backcross progenyplants that have the desired trait(s) and physiological andmorphological characteristics of bean cultivar H24953 to produceselected backcross progeny plants; and (e) repeating steps (c) and (d)one, two, three, four, five six, seven, eight, nine or more times insuccession to produce selected, second, third, fourth, fifth, sixth,seventh, eighth, ninth or higher backcross progeny plants that comprisethe desired trait(s) and the physiological and morphologicalcharacteristics of bean cultivar H24953 as determined in Table one at a5% significance level when grown in the same environmental conditions.The bean plants produced by the methods are also part of the invention.Backcrossing breeding methods, well-known for a man skilled in the artof plant breeding, will be further developed in subsequent parts of thespecification.

In a preferred embodiment, the present invention provides methods forincreasing and producing bean cultivar H24953 seed, whether by crossinga first parent bean cultivar plant with a second parent bean cultivarplant and harvesting the resultant bean seed, wherein both said firstand second parent bean cultivar plant are the bean cultivar H24953 or byplanting a bean seed of the bean cultivar H24953, growing a beancultivar H24953 plant from said seed, controlling a self pollination ofthe plant where the pollen produced by a grown bean cultivar H24953plant pollinates the ovules produced by the very same bean cultivarH24953 grown plant and harvesting the resultant seed.

The invention further provides methods for developing bean cultivars ina bean breeding program using plant breeding technique includingrecurrent selection, backcrossing, pedigree breeding, molecular markers(Isozyme Electrophoresis, Restriction Fragment Length Polymorphisms(RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily PrimedPolymerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting(DAF), Sequence Characterized Amplified Regions (SCARs). AmplifiedFragment Length Polymorphisms (AFLPs), and Simple Sequence Repeats(SSRs) which are also referred to as Microsatellites, etc.) enhancedselection, genetic marker enhanced selection and transformation.

DETAILED DESCRIPTION OF THE INVENTION

Garden bean cultivar H24953 has superior characteristics and wasdeveloped from an initial cross that was made in the San Juan Bautista(SJB), Calif., Harris Moran Seed Company research station greenhouse inthe Spring of 1998. The cross was between two proprietary lines understake numbers M3652 (female) and M3613 (male). The F₁ generation washarvested in September 1998 at the Harris Moran research grounds at SanJuan Bautista, Calif. in plot 4X184-3. The F₂ selection was made inFebruary 1999 at the Harris Moran research grounds near Los Mochis,Mexico in plot 5LA1580. The F₃ selection was made in July 1999 at theHarris Moran research grounds near Coloma, Wis. in plot 5YE7881. The F₄selection was made in July 2000 at the Harris Moran research groundsnear Coloma, Wis. in plot 6YE5830. The F₅ selection was made in February2001 at the Harris Moran research grounds near Los Mochis, Mexico inplot 7L0830. The F₆ selection was made in July 2001 at the Harris Moranresearch grounds near Coloma, Wis. in plot 7Y8342. The F₇ generation wasbulked in February 2002 at the Harris Moran research grounds near LosMochis, Mexico in plot M21267. The F₈ generation was bulked in September2002 at the Harris Moran research grounds at San Juan Bautista, Calif.in plot C201842. The F₉ generation was bulked in February 2003 at theHarris Moran research grounds near Los Mochis, Mexico in plot M31690.The F₁₀ generation was harvested as 135 single plants in September 2003at the Harris Moran research grounds at San Juan Bautista, Calif. inplot C305952. The single plants were indexed to confirm fixed resistanceto Uromyces appendiculatus in October 2003 in the greenhouse at SunPrairie, Wis. Harris Moran research station. The F₁₁ generation wasbulked in February 2004 at the Harris Moran research grounds near LosMochis, Mexico in plot M43501-43635. The line was designated H24953.

Garden bean cultivar H24953 is similar to garden bean cultivar‘Caprice’. While similar to garden bean cultivar ‘Caprice, there aresignificant differences including garden bean cultivar H24953 has darkergreen pods that are smaller in diameter than ‘Caprice’. In addition,garden bean cultivar H24953 reaches maturity three days later than‘Caprice’.

H24953 is a 60 days late maturity bean with uniform dark green pods onan upright plant structure. The majority of the pods are in the 3 sievesrange. The leaves are medium in size with a dark semi glossy greencolor. H24953 is a determinate plant and is resistant to Bean CommonMosaic Virus (BCMV I-gene), Pseudomonas syringae pv. syringae (bacterialbrown spot), Uromyces appendiculatus races 38, 53 and 72, and Beat CurlyTop Virus. H24953 has intermediate resistance to Pseudomonas syringaepv. phaseolicola and to Xanthomonas campestris (common bacterialblight).

Some of the selection criteria used for various generations include: podappearance and length, bean yield, pod set height, emergence, maturity,plant architecture, habit and height, seed yield and quality and diseaseresistance.

Bean Common Mosaic Virus resistance is a desired trait for a beanvariety. The disease occurs worldwide causing low quality of the harvestproduct and losses from 80% to 100% by reduction of yield. It is mostlytransmitted by aphids during the growing season, but can also be spreadby pollen or mechanically. The leaves develop mosaic patterns in whichirregular light and dark green patches are intermixed. Malformation andyellow dots may also be produced, often causing growth reduction. Theplant may be dwarfed and pod and seed yield reduced. Severe necrosis mayoccur and the plant may die if infected while young. Systemic necrosis,in which the roots and shoots become blackened, appears in cultivarshaving a dominant resistance gene (hypersensitive resistance mechanism).The systemic necrosis may spread to higher leaves without killing themor may be concentrated in the vascular parts of the stem, eventuallyleading to the death of all or part of the plant. When infection occurslate in plant development, parts of the plant may die and many pods mayshow brown discoloration in the pod wall and pod suture as a result ofvascular necrosis.

Bacterial Brown Spot is a bacterial disease that can severely damagebean fields. Brown Spot is caused by Pseudomonas syringae pv. syringae.The plant may suffer multiple lesions on the leaves (circular, brown andnecrotic) but also the on stems and pods.

Another major bacterial disease is the common bacterial blight thataffects the foliage and the pods of beans. The disease caused byXanthomonas campestris pv. phaseoli, which can cause yield losses aswell as losses in seed quality. The major source of primary inoculum isseeds that are contaminated when planted.

Garden bean cultivar H24953 has shown uniformity and stability for thetraits, as described in the following Variety Description Information.It has been self-pollinated a sufficient number of generations withcareful attention to uniformity of plant type. The cultivar has beenincreased with continued observation for uniformity. No variant traitshave been observed or are expected in garden bean cultivar H249553.

Garden bean cultivar H24953 has the following morphologic and othercharacteristics (based primarily on data collected at Sun Prairie, Wis.Research Station).

Further, both first and second parent bean plants cancome from cultivar H24953. When self pollinated, or crossed with anotherbean cultivar H24953 plant, the bean cultivar H24953 will be stable,while when crossed with another, different bean cultivar plant, an F₁hybrid seed is produced.

Still further, this invention also is directed to methods for producingan H24953-derived bean plant by crossing cultivar H24953 with a secondbean plant and growing the progeny seed, and repeating the crossing andgrowing steps with the cultivar H24953-derived plant from 0 to 7 times.Thus, any such methods using the cultivar H24953 are part of thisinvention: selfing, backcrosses, hybrid production, crosses topopulations, and the like. All plants produced using cultivar H24953 asa parent are within the scope of this invention, including plantsderived from cultivar H24953. Advantageously, the cultivar is used incrosses with other, different, cultivars to produce first generation(F₁) bean seeds and plants with superior characteristics.

As used herein, the term “plant” includes plant cells, plantprotoplasts, plant cell tissue cultures from which garden bean plantscan be regenerated, plant calli, plant clumps and plant cells that areintact in plants or parts of plants, such as embryos, pollen, ovules,flowers, seeds, pods, stems, roots, anthers, pistils, root tips, leavesand the like.

Thus, anotheraspect of this invention is to provide cells which upon growth anddifferentiation produce bean plants having the physiological andmorphological characteristics of garden bean cultivar H24953.

As used herein, the term “tissue culture” indicates a compositioncomprising isolated cells of the same or a different type or acollection of such cells organized into parts of a plant. Exemplarytypes of tissue cultures are protoplasts, calli, plant clumps, and plantcells that can generate tissue culture that are intact in plants orparts of plants, such as embryos, pollen, flowers, seeds, pods, leaves,stems, roots, root tips, anthers, pistils and the like. Means forpreparing and maintaining plant tissue culture are well known in theart. By way of example, a tissue culture comprising organs has been usedto produce regenerated plants. U.S. Pat. Nos. 5,959,185; 5,973,234 and5,977,445 describe certain techniques, the disclosures of which areincorporated herein by reference.

With the advent of molecular biological techniques that have allowed theisolation and characterization of genes that encode specific proteinproducts, scientists in the field of plant biology developed a stronginterest in engineering the genome of plants to contain and expressforeign genes, or additional, or modified versions of native, orendogenous, genes (perhaps driven by different promoters) in order toalter the traits of a plant in a specific manner. Such foreignadditional and/or modified genes are referred to herein collectively as“transgenes”. Over the last fifteen to twenty years several methods forproducing transgenic plants have been developed and the presentinvention, in particular embodiments, also relates to transformedversions of the claimed variety or line.

Plant transformation involves the construction of an expression vectorwhich will function in plant cells. Such a vector comprises DNAcomprising a gene under control of, or operatively linked to, aregulatory element (for example, a promoter). The expression vector maycontain one or more such operably linked gene/regulatory elementcombinations. The vector(s) may be in the form of a plasmid and can beused alone or in combination with other plasmids to provide transformedgarden bean plants using transformation methods as described below toincorporate transgenes into the genetic material of the garden beanplant(s).

Expression Vectors for Garden Bean Transformation: Marker Genes

Expression vectors include at least one genetic marker operably linkedto a regulatory element (a promoter, for example) that allowstransformed cells containing the marker to be either recovered bynegative selection, i.e., inhibiting growth of cells that do not containthe selectable marker gene, or by positive selection, i.e., screeningfor the product encoded by the genetic marker. Many commonly usedselectable marker genes for plant transformation are well known in thetransformation arts, and include, for example, genes that code forenzymes that metabolically detoxify a selective chemical agent which maybe an antibiotic or an herbicide, or genes that encode an altered targetwhich is insensitive to the inhibitor. A few positive selection methodsare also known in the art.

One commonly used selectable marker gene for plant transformation is theneomycin phosphotransferase II (nptII) gene which, when under thecontrol of plant regulatory signals, confers resistance to kanamycin.Fraley et al., Proc. Natl. Acad. Sci. USA, 80:4803 (1983). Anothercommonly used selectable marker gene is the hygromycinphosphotransferase gene which confers resistance to the antibiotichygromycin. Vanden Elzen et al., Plant Mol. Biol., 5:299 (1985).

Additional selectable marker genes of bacterial origin that conferresistance to antibiotics include gentamycin acetyl transferase,streptomycin phosphotransferase and aminoglycoside-3′-adenyltransferase, the bleomycin resistance determinant (Hayford et al., PlantPhysiol. 86:1216 (1988), Jones et al., Mol. Gen. Genet., 210:86 (1987),Svab et al., Plant Mol. Biol. 14:197 (1990), Hille et al., Plant Mol.Biol. 7:171 (1986)). Other selectable marker genes confer resistance toherbicides such as glyphosate, glufosinate or bromoxynil (Comai et al.,Nature 317:741-744 (1985), Gordon-Kamm et al., Plant Cell 2:603-618(1990) and Stalker et al., Science 242:419-423 (1988)).

Other selectable marker genes for plant transformation are not ofbacterial origin. These genes include, for example, mouse dihydrofolatereductase, plant 5-enolpyruvylshikimate-3-phosphate synthase and plantacetolactate synthase. Eichholtz et al., Somatic Cell Mol. Genet. 13:67(1987), Shah et al., Science 233:478 (1986), Charest et al., Plant CellRep. 8:643 (1990).

Another class of marker genes for plant transformation requiresscreening of presumptively transformed plant cells rather than directgenetic selection of transformed cells for resistance to a toxicsubstance such as an antibiotic. These genes are particularly useful toquantify or visualize the spatial pattern of expression of a gene inspecific tissues and are frequently referred to as reporter genesbecause they can be fused to a gene or gene regulatory sequence for theinvestigation of gene expression. Commonly used genes for screeningpresumptively transformed cells include β-glucuronidase (GUS),β-galactosidase, luciferase and chloramphenicol acetyltransferase(Jefferson, R. A., Plant Mol. Biol. Rep. 5:387 (1987), Teeri et al.,EMBO J. 8:343 (1989), Koncz et al., Proc. Natl. Acad. Sci. USA 84:131(1987), DeBlock et al., EMBO J. 3:1681 (1984)).

In vivo methods for visualizing GUS activity that do not requiredestruction of plant tissue are available. However, these in vivomethods for visualizing GUS activity have not proven useful for recoveryof transformed cells because of low sensitivity, high fluorescentbackgrounds and limitations associated with the use of luciferase genesas selectable markers.

A gene encoding Green Fluorescent Protein (GFP) has been utilized as amarker for gene expression in prokaryotic and eukaryotic cells (Chalfieet al., Science 263:802 (1994)). GFP and mutants of GFP may be used asscreenable markers.

Expression Vectors for Garden bean Transformation: Promoters

Genes included in expression vectors must be driven by a nucleotidesequence comprising a regulatory element, for example, a promoter.Several types of promoters are well known in the transformation arts asare other regulatory elements that can be used alone or in combinationwith promoters.

As used herein, “promoter” includes reference to a region of DNAupstream from the start of transcription and involved in recognition andbinding of RNA polymerase and other proteins to initiate transcription.A “plant promoter” is a promoter capable of initiating transcription inplant cells. Examples of promoters under developmental control includepromoters that preferentially initiate transcription in certain tissues,such as leaves, roots, seeds, fibers, xylem vessels, tracheids, orsclerenchyma. Such promoters are referred to as “tissue-preferred”.Promoters that initiate transcription only in a certain tissue arereferred to as “tissue-specific”. A “cell-type” specific promoterprimarily drives expression in certain cell types in one or more organs,for example, vascular cells in roots or leaves. An “inducible” promoteris a promoter which is under environmental control. Examples ofenvironmental conditions that may effect transcription by induciblepromoters include anaerobic conditions or the presence of light.Tissue-specific, tissue-preferred, cell type specific, and induciblepromoters constitute the class of “non-constitutive” promoters. A“constitutive” promoter is a promoter that is active under mostenvironmental conditions.

A. Inducible Promoters—An inducible promoter is operably linked to agene for expression in garden bean. Optionally, the inducible promoteris operably linked to a nucleotide sequence encoding a signal sequencewhich is operably linked to a gene for expression in garden bean. Withan inducible promoter the rate of transcription increases in response toan inducing agent.

Any inducible promoter can be used in the instant invention. See Ward etal., Plant Mol. Biol. 22:361-366 (1993). Exemplary inducible promotersinclude, but are not limited to, that from the ACEI system whichresponds to copper (Mett et al., Proc. Natl. Acad. Sci. USA 90:4567-4571(1993)); In2 gene from maize which responds to benzenesulfonamideherbicide safeners (Gatz et al., Mol. Gen. Genetics 243:32-38 (1994)) orTet repressor from Tn10 (Gatz et al., Mol. Gen. Genetics 227:229-237(1991)). A particularly preferred inducible promoter is a promoter thatresponds to an inducing agent to which plants do not normally respond.An exemplary inducible promoter is the inducible promoter from a steroidhormone gene, the transcriptional activity of which is induced by aglucocorticosteroid hormone (Schena et al., Proc. Natl. Acad. Sci. USA88:0421 (1991)).

B. Constitutive Promoters—A constitutive promoter is operably linked toa gene for expression in garden bean or the constitutive promoter isoperably linked to a nucleotide sequence encoding a signal sequencewhich is operably linked to a gene for expression in garden bean.

Many different constitutive promoters can be utilized in the instantinvention. Exemplary constitutive promoters include, but are not limitedto, the promoters from plant viruses such as the 35S promoter from CaMV(Odell et al., Nature 313:810-812 (1985)) and the promoters from suchgenes as rice actin (McElroy et al., Plant Cell 2: 163-171 (1990));ubiquitin (Christensen et al., Plant Mol. Biol. 12:619-632 (1989) andChristensen et al., Plant Mol. Biol. 18:675-689 (1992)); pEMU (Last etal., Theor. Appl. Genet. 81:581-588 (1991)); MAS (Velten et al., EMBO J.3:2723-2730 (1984)) and maize H3 histone (Lepetit et al., Mol. Gen.Genetics 231:276-285 (1992) and Atanassova et al., Plant Journal 2 (3):291-300 (1992)). The ALS promoter, Xba1/NcoI fragment 5′ to the Brassicanapus ALS3 structural gene (or a nucleotide sequence similarity to saidXba1/NcoI fragment), represents a particularly useful constitutivepromoter. See PCT application WO 96/30530.

C. Tissue-specific or Tissue-preferred Promoters—A tissue-specificpromoter is operably linked to a gene for expression in garden bean.Optionally, the tissue-specific promoter is operably linked to anucleotide sequence encoding a signal sequence which is operably linkedto a gene for expression in garden bean. Plants transformed with a geneof interest operably linked to a tissue-specific promoter produce theprotein product of the transgene exclusively, or preferentially, in aspecific tissue.

Any tissue-specific or tissue-preferred promoter can be utilized in theinstant invention. Exemplary tissue-specific or tissue-preferredpromoters include, but are not limited to, a root-preferred promotersuch as that from the phaseolin gene (Murai et al., Science 23:476-482(1983) and Sengupta-Gopalan et al., Proc. Natl. Acad. Sci. USA82:3320-3324 (1985)); a leaf-specific and light-induced promoter such asthat from cab or rubisco (Simpson et al., EMBO J. 4(11):2723-2729 (1985)and Timko et al., Nature 318:579-582 (1985)); an anther-specificpromoter such as that from LAT52 (Twell et al., Mol. Gen. Genetics217:240-245 (1989)); a pollen-specific promoter such as that from Zm13or a microspore-preferred promoter such as that from apg (Twell et al.,Sex. Plant Reprod. 6:217-224 (1993)).

Signal Sequences for Targeting Proteins to Subcellular Compartments

Transport of protein produced by transgenes to a subcellular compartmentsuch as the chloroplast, vacuole, peroxisome, glyoxysome, cell wall ormitochondrion or for secretion into the apoplast, is accomplished bymeans of operably linking the nucleotide sequence encoding a signalsequence to the 5′ and/or 3′ region of a gene encoding the protein ofinterest. Targeting sequences at the 5′ and/or 3′ end of the structuralgene may determine during protein synthesis and processing where theencoded protein is ultimately compartmentalized.

The presence of a signal sequence directs a polypeptide to either anintracellular organelle or subcellular compartment or for secretion tothe apoplast. Many signal sequences are known in the art. See, forexample, Becker et al., Plant Mol. Biol. 20:49 (1992); Knox, C., et al.,“Structure and Organization of Two Divergent Alpha-Amylase Genes fromBarley”, Plant Mol. Biol. 9:3-17 (1987); Lerner et al., Plant Physiol.91:124-129 (1989); Fontes et al., Plant Cell 3:483-496 (1991); Matsuokaet al., Proc. Natl. Acad. Sci. 88:834 (1991); Gould et al., J. Cell.Biol. 108:1657 (1989); Creissen et al., Plant J. 2:129 (1991); Kalderon,et al., Cell 39:499-509 (1984); Steifel, et al., “Expression of a maizecell wall hydroxyproline-rich glycoprotein gene in early leaf and rootvascular differentiation”, Plant Cell 2:785-793 (1990).

Foreign Protein Genes and Agronomic Genes

With transgenic plants according to the present invention, a foreignprotein can be produced in commercial quantities. Thus, techniques forthe selection and propagation of transformed plants, which are wellunderstood in the art, yield a plurality of transgenic plants which areharvested in a conventional manner, and a foreign protein then can beextracted from a tissue of interest or from total biomass. Proteinextraction from plant biomass can be accomplished by known methods whichare discussed, for example, by Heney and Orr, Anal. Biochem. 114:92-6(1981).

According to a preferred embodiment, the transgenic plant provided forcommercial production of foreign protein is a garden bean plant. Inanother preferred embodiment, the biomass of interest is seed. For therelatively small number of transgenic plants that show higher levels ofexpression, a genetic map can be generated, primarily via conventionalRFLP, PCR and SSR analysis, which identifies the approximate chromosomallocation of the integrated DNA molecule. For exemplary methodologies inthis regard, see Glick and Thompson, Methods in Plant Molecular Biologyand Biotechnology, CRC Press, Boca Raton 269:284 (1993). Map informationconcerning chromosomal location is useful for proprietary protection ofa subject transgenic plant. If unauthorized propagation is undertakenand crosses made with other germplasm, the map of the integration regioncan be compared to similar maps for suspect plants, to determine if thelatter have a common parentage with the subject plant. Map comparisonswould involve hybridizations, RFLP, PCR, SSR and sequencing, all ofwhich are conventional techniques.

Likewise, by means of the present invention, agronomic genes can beexpressed in transformed plants. More particularly, plants can begenetically engineered to express various phenotypes of agronomicinterest. Exemplary genes implicated in this regard include, but are notlimited to, those categorized below:

1. Genes That Confer Resistance to Pests or Disease and That Encode:

Plant defenses are often activated byspecific interaction between the product of a disease resistance gene(R) in the plant and the product of a corresponding avirulence (Avr)gene in the pathogen. A plant variety can be transformed with one ormore cloned resistance genes to engineer plants that are resistant tospecific pathogen strains. See, for example Jones et al., Science266:789 (1994) (cloning of the tomato Cf-9 gene for resistance toCladosporium fulvum); Martin et al., Science 262:1432 (1993) (tomato Ptogene for resistance to Pseudomonas syringae pv. tomato encodes a proteinkinase); Mindrinos et al.

N. A viral-invasive protein or a complex toxin derived therefrom. Forexample, the accumulation of viral coat proteins in transformed plantcells imparts resistance to viral infection and/or disease developmenteffected by the virus from which the coat protein gene is derived, aswell as by related viruses.

2. Genes That Confer Resistance to an Herbicide, for Example:

A. An herbicide that inhibits the growing point or meristem, such as animidazolinone or a sulfonylurea. Exemplary genes in this category codefor mutant ALS and AHAS enzyme as described, for example, by Lee et al.,EMBO J. 7:1241 (1988), and Miki et al., Theor. Appl. Genet. 80:449(1990), respectively.

B. Glyphosate (resistance conferred by mutant5-enolpyruvlshikimate-3-phosphate synthase (EPSPS) and aroA genes,respectively) and other phosphono compounds such as glufosinate(phosphinothricin acetyl transferase (PAT) and Streptomyceshygroscopicus PAT bar genes), and pyridinoxy or phenoxy proprionic acidsand cyclohexones (ACCase inhibitor-encoding genes). See, for example,U.S. Pat. No. 4,940,835 to Shah, et al., which discloses the nucleotidesequence of a form of EPSPS which can confer glyphosate resistance. ADNA molecule encoding a mutant aroA gene can be obtained under ATCCaccession number 39256, and the nucleotide sequence of the mutant geneis disclosed in U.S. Pat. No. 4,769,061 to Comai.

Appl. Genet. 83:435 (1992).

The protoxenzyme serves as the target for a variety of herbicidal compounds. Theseherbicides also inhibit growth of all the different species of plantspresent, causing their total destruction. The development of plantscontaining altered protox activity which are resistant to theseherbicides are described in U.S. Pat.

Methods for Garden Bean Transformation

Numerous methods for plant transformation have been developed includingbiological and physical plant transformation protocols. See, forexample, Miki et al., “Procedures for Introducing Foreign DNA intoPlants” in Methods in Plant Molecular Biology and Biotechnology, Glick,B. R. and Thompson, J. E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages67-88. In addition, expression vectors and in-vitro culture methods forplant cell or tissue transformation and regeneration of plants areavailable. See, for example, Gruber et al., “Vectors for PlantTransformation” in Methods in Plant Molecular Biology and Biotechnology,Glick, B. R. and Thompson, J. E. Eds. (CRC Press, Inc., Boca Raton,1993) pages 89-119.

A. Agrobacterium-mediated Transformation—One method for introducing anexpression vector into plants is based on the natural transformationsystem of Agrobacterium. See, for example, Horsch et al., Science227:1229 (1985); Diant et al., Molecular Breeding 3:1, 75-86 (1997). A.tumefaciens and A. rhizogenes are plant pathogenic soil bacteria whichgenetically transform plant cells. The Ti and Ri plasmids of A.tumefaciens and A. rhizogenes, respectively, carry genes responsible forgenetic transformation of the plant. See, for example, Kado, C. I.,Crit. Rev. Plant Sci. 10:1 (1991). Descriptions of Agrobacterium vectorsystems and methods for Agrobacterium mediated gene transfer areprovided by Gruber et al., supra, Miki et al., supra and Moloney et al.,Plant Cell Reports 8:238 (1989). See also, U.S. Pat. No. 5,591,616issued Jan. 7, 1997.

B. Direct Gene Transfer—Despite the fact the host range forAgrobacterium-mediated transformation is broad, some cereal or vegetablecrop species and gymnosperms have generally been recalcitrant to thismode of gene transfer, even though some success has been achieved inrice and corn. Hiei et al., The Plant Journal 6:271-282 (1994) and U.S.Pat. No. 5,591,616 issued January 7, 1997. Several methods of planttransformation, collectively referred to as direct gene transfer, havebeen developed as an alternative to Agrobacterium-mediatedtransformation. A generally applicable method of plant transformation ismicroprojectile-mediated transformation where DNA is carried on thesurface of microprojectiles measuring 1 to 4 microns. The expressionvector is introduced into plant tissues with a biolistic device thataccelerates the microprojectiles to speeds of 300 to 600 m/s which issufficient to penetrate plant cell walls and membranes. Russell, D. R.,et al. Pl. Cell. Rep. 12(3, January), 165-169 (1993), Aragao, F. J. L.,et al. Plant Mol. Biol. 20(2, October.), 357-359 (1992), Aragao Theor.Appl. Genet. 93: 142-150 (1996), Kim, J.; Minamikawa, T. Plant Science117: 131-138 (1996), Sanford et al., Part. Sci. Technol. 5:27 (1987);Sanford, J. C., Trends Biotech. 6:299 (1988); Klein et al., Bio/Tech.6:559-563 (1988); Sanford, J. C. Physiol Plant 7:206 (1990); Klein etal., Biotechnology 10:268 (1992).

Another method for physical delivery of DNA to plants is sonication oftarget cells. Zhang et al., Bio/Technology 9:996 (1991). Alternatively,liposome and spheroplast fusion have been used to introduce expressionvectors into plants. Deshayes et al., EMBO J., 4:2731 (1985); Christouet al., Proc Natl. Acad. Sci. USA 84:3962 (1987). Direct uptake of DNAinto protoplasts using CaCl₂ precipitation, polyvinyl alcohol orpoly-L-ornithine have also been reported. Hain et al., Mol. Gen. Genet.199:161 (1985) and Draper et al., Plant Cell Physiol. 23:451 (1982).Electroporation of protoplasts and whole cells and tissues have alsobeen described Saker, M and Kuhne, T. Biologia Plantarum 40(4): 507-514(1997/98); D'Halluin et al., Plant Cell 4:1495-1505 (1992) and Spenceret al., Plant Mol. Biol. 24:51-61 (1994)).

Following transformation of garden bean target tissues, expression ofthe above-described selectable marker genes allows for preferentialselection of transformed cells, tissues and/or plants, usingregeneration and selection methods well known in the art.

The foregoing methods for transformation would typically be used forproducing a transgenic variety. The transgenic variety could then becrossed with another (non-transformed or transformed) variety in orderto produce a new transgenic variety. Alternatively, a genetic trait thathas been engineered into a particular garden bean line using theforegoing transformation techniques could be moved into another lineusing traditional backcrossing techniques that are well known in theplant breeding arts. For example, a backcrossing approach could be usedto move an engineered trait from a public, non-elite variety into anelite variety, or from a variety containing a foreign gene in its genomeinto a variety or varieties that do not contain that gene. As usedherein, “crossing” can refer to a simple X by Y cross or the process ofbackcrossing depending on the context.

Backcrossing

When the term garden bean plant, cultivar or bean line are used in thecontext of the present invention, this also includes cultivars where oneor more desired traits has been introduced through backcrossing methods,whether such trait is a naturally occurring one or a transgenic one.Backcrossing methods can be used with the present invention to improveor introduce a characteristic into the line. The term “backcrossing” asused herein refers to the repeated crossing of a hybrid progeny back tothe recurrent parent, i.e. backcrossing 1, 2, 3, 4, 5, 6, 7, 8, 9 ormore times to the recurrent parent. The parental bean plant whichcontributes the gene for the desired characteristic is termed thenonrecurrent or donor parent. This terminology refers to the fact thatthe nonrecurrent parent is used one time in the backcross protocol andtherefore does not recur. The parental bean plant to which the gene orgenes from the nonrecurrent parent are transferred is known as therecurrent parent as it is used for several rounds in the backcrossingprotocol.

In a typical backcross protocol, the original cultivar of interest(recurrent parent) is crossed to a second line (nonrecurrent parent)that carries the gene or genes of interest to be transferred. Theresulting progeny from this cross are then crossed again to therecurrent parent and the process is repeated until a garden bean plantis obtained wherein essentially all of the desired morphological andphysiological characteristics of the recurrent parent are recovered inthe converted plant, generally determined at a 5% significance levelwhen grown in the same environmental condition, in addition to the geneor genes transferred from the nonrecurrent parent. It has to be notedthat some, one, two, three or more, self-pollination and growing ofpopulation might be included between two successive backcrosses. Indeed,an appropriate selection in the population produced by theself-pollination, i.e. selection for the desired trait and physiologicaland morphological characteristics of the recurrent parent might beequivalent to one, two or even three, additional backcrosses in acontinuous series without rigorous selection, saving time, money andeffort to the breeder. A non limiting example of such a protocol wouldbe the following: a) the first generation F₁ produced by the cross ofthe recurrent parent A by the donor parent B is backcrossed to parent A;b) selection is practiced for the plants having the desired trait ofparent B; c) selected plants are self-pollinated to produce a populationof plants where selection is practiced for the plants having the desiredtrait of parent B and the physiological and morphologicalcharacteristics of parent A; d) the selected plants are backcrossed one,two, three, four, five, six, seven, eight, nine or more times to parentA to produce selected backcross progeny plants comprising the desiredtrait of parent B and the physiological and morphologicalcharacteristics of parent A. Step c) may or may not be repeated andincluded between the backcrosses of step d.

The selection of a suitable recurrent parent is an important step for asuccessful backcrossing procedure. The goal of a backcross protocol isto alter or substitute a single trait or characteristic in the originalline. To accomplish this, a gene or genes of the recurrent cultivar ismodified or substituted with the desired gene from the nonrecurrentparent, while retaining essentially all of the rest of the desiredgenetic, and therefore the desired physiological and morphological,constitution of the original line. The choice of the particularnonrecurrent parent will depend on the purpose of the backcross, one ofthe major purposes is to add some commercially desirable, agronomicalimportant trait to the plant. The exact backcrossing protocol willdepend on the characteristic or trait being altered to determine anappropriate testing protocol. Although backcrossing methods aresimplified when the characteristic being transferred is a single geneand dominant allele, multiple genes and recessive allele(s) may also betransferred and therefore, backcross breeding is by no means restrictedto character(s) governed by one or a few genes. In fact the number ofgenes might be less important that the identification of thecharacter(s) in the segregating population. In this instance it may thenbe necessary to introduce a test of the progeny to determine if thedesired characteristic(s) has been successfully transferred. Such testsencompass visual inspection, simple crossing but also follow up of thecharacteristic(s) through genetically associated markers and molecularassisted breeding tools. For example, selection of progeny containingthe transferred trait is done by direct selection, visual inspection fora trait associated with a dominant allele, while the selection ofprogeny for a trait that is transferred via a recessive allele requireselfing the progeny to determine which plant carry the recessiveallele(s).

Many single gene traits have been identified that are not regularlyselected for in the development of a new line but that can be improvedby backcrossing techniques. Single gene traits may or may not betransgenic, examples of these traits include but are not limited to,herbicide resistance (such as bar or pat genes), resistance forbacterial, fungal, or viral disease such as gene I used for BCMVresistance), insect resistance, enhanced nutritional quality (such as 2salbumine gene), industrial usage, agronomic qualities such as the“persistent green gene”, yield stability and yield enhancement. Thesegenes are generally inherited through the nucleus. Some other singlegene traits are described in U.S. Pat. Nos. 5,777,196; 5,948,957 and5,969,212, the disclosures of which are specifically hereby incorporatedby reference.

In 1981 the backcross method of breeding accounted for 17% of the totalbreeding effort for inbred corn line development in the United States,according to, Hallauer, A. R. et al. (1988) “Corn Breeding” Corn andCorn Improvement, No. 18, pp. 463-481.

The backcross breeding method provides a precise way of improvingvarieties that excel in a large number of attributes but are deficientin a few characteristics. (Page 150 of the Pr. R. W. Allard's 1960 book,published by John Wiley & Sons, Inc, Principles of Plant Breeding). Themethod makes use of a series of backcrosses to the variety to beimproved during which the character or the characters in whichimprovement is sought is maintained by selection. At the end of thebackcrossing the gene or genes being transferred unlike all other genes,will be heterozygous. Selfing after the last backcross produceshomozygosity for this gene pair(s) and, coupled with selection, willresult in a variety with exactly the adaptation, yielding ability andquality characteristics of the recurrent parent but superior to thatparent in the particular characteristic(s) for which the improvementprogram was undertaken. Therefore, this method provides the plantbreeder with a high degree of genetic control of his work.

The backcross method is scientifically exact because the morphologicaland agricultural features of the improved variety could be described inadvance and because the same variety could, if it were desired, be breda second time by retracing the same steps (Briggs, “Breeding wheatsresistant to bunt by the backcross method”, 1930 Jour. Amer. Soc.Agron., 22: 289-244).

Backcrossing is a powerful mechanism for achieving homozygosity and anypopulation obtained by backcrossing must rapidly converge on thegenotype of the recurrent parent. When backcrossing is made the basis ofa plant breeding program, the genotype of the recurrent parent will bemodified only with regards to genes being transferred, which aremaintained in the population by selection.

Successful backcrosses are for example, the transfer of stem rustresistance from “Hope” wheat to “Bart” wheat and even pursuing thebackcrosses with the transfer of bunt resistance to create “Bart 38”,having both resistances. Also highlighted by Allard is the successfultransfer of mildew, leaf spot and wilt resistances in “CaliforniaCommon” alfalfa to create “Caliverde”. This new “Caliverde” varietyproduced through the backcross process is indistinguishable from“California Common” except for its resistance to the three nameddiseases.

One of the advantages of the backcross method is that the breedingprogram can be carried out in almost every environment that will allowthe development of the character being transferred.

The backcross technique is not only desirable when breeding for diseaseresistance but also for the adjustment of morphological characters,color characteristics and simply inherited quantitative characters suchas earliness, plant height and seed size and shape. In this regard, amedium grain type variety, “Calady”, has been produced by Jones andDavis. As dealing with quantitative characteristics, they selected thedonor parent with the view of sacrificing some of the intensity of thecharacter for which it was chosen, i.e. grain size. “Lady Wright”, along grain variety was used as the donor parent and “Coloro”, a shortgrain one as the recurrent parent. After four backcrosses, the mediumgrain type variety “Calady” was produced.
